Abstract (en)
[origin: CN114379070A] The invention relates to an improved longitudinal stretching device, which is characterized by the following features: in addition to a mounting or operating position (A) for a structural unit (21) to be replaced, the longitudinal stretching device further comprises a preparation position (D) and/or a preparation station (19), in which a further structural unit (21) is prepared; the preparation position (D) and/or the preparation station (19) are/is arranged and/or designed with respect to the longitudinal stretching mechanism. According to the invention, the further component unit (21) prepared at the preparation position (D) and/or the preparation station (19) has reached or can reach an operating temperature or at least reaches a preheating temperature which is higher than the operating temperature or less than 30 DEG C lower than the operating temperature before being installed in the operating position (A). By means of the solution according to the invention, a simple and in particular less complicated replacement of the component to be replaced and in particular the roller can be achieved.
